Roll-forming is the process of transforming steel strip into profiles. The steel strip is cold-formed step by step over a number of roll-forming stations by means of upper, bottom and side rolls. It is a continuous process, each roll is responsible for the subsequent step in the transformation of the steel strip to its final form. Sadef's roll-forming process integrates strip and post piercing, allows for online high-frequency and laser welding, integrates mechanical connections, and yields profiles cut to actual length.
Sadef profiles are manufactured from the appropriate material (pickled, pre-galvanised, pre-painted, stainless steel) and can be provided with integrated functions through the integration of online piercing. The special formed profiles can finally also be provided with a suitable surface treatment (cataphoresis and powder painting).
Sadef is also your ideal partner for special formed tubes!
Our roll-forming process supports the manufacture of tube profiles from steel strip by high-frequency or laser welding. We can also deliver closed profiles via mechanical connections (including riveting and clinching). Joints on pre-galvanised profiles are post-treated inline. Different steel components can be joined offline by MIG or TIG welding.
